Hello!
Some comments on this experiment. The aim was to create an underwater athmosphere mainly with mlcad, ldraw, lpub functionality and only little changes on the resulting povray code. And I limited myself to parts which are available according to peeron. (This lead to the strange jellyfish ;-) )
There are 6 to 7 lightsources placed above the scenery and between the lightsources and the fish is a layer of 1x2 bricks in clear, transgreen and trans light blue for scattering the light.
In the povray source I've changed two things:
1. Pump up the light sources with a factor of 4 or 5 like
light_source {
color rgb 4* <0.8,0.666667,0.4>
//shadowless
}
2. Adding fog (I really like that :-) )
fog {
distance 1000
color rgb<0.5, 0.95, 0.8>
}
I would like to say to all the people developing ldraw, mlcad, lpub, povray, megapov and further tools that I really admire their voluntary work.
============================================
changes for a better result:
1. added light sources and changed them to spotlight.
2. Increased the size of the layer of 2x1-Transcolor Bricks.
Now the layer is visible as the "surface" of the water.
3. Added some tan base plates in the background and 1x1 round plates for a better ground.
4. Increased the distance between light sources and Transcolor bricks layer for a more realistic effect of the light scattering on the ground. (Whatever a "realistic" effect might be in virtual lego).
